In a food processor, pulse cookies until fine crumbs. Add melted butter and stir until combined. Press into bottom of prepared dish.
In a large mixing bowl, add white chocolate chips and marshmallow cream. Set aside.
In a large saucepan, combine sugar, butter, salt and cream. Heat over medium high heat, stirring constantly, until mixture begins to boil. Continue boiling for 4-5 minutes (at a rolling boil). Remove from heat and pour over chocolate chips and marshmallow cream.
Using an electric mixer, beat mixture until white chocolate chips are melted and fudge is creamy (about 1-2 minutes). Add strawberry preserves and stir gently until swirled in. Pour over crust. Refrigerate fudge for 4 hours. Cut and serve!
Notes
How to store: Keep strawberry shortcake fudge in an airtight container at room temperature or in the fridge. I recommend storing UNCUT for best freshness. Cut a little at a time; only what you’re eating or serving immediately.
How to freeze fudge: Wrap uncut fudge in plastic cling wrap. Then place in a freezer safe bag. It’ll keep well for 2 months. Let thaw at room temperature or in the fridge before cutting.
Use an electric mixer: Beaters or a stand mixer help incorporate the fudge ingredients quickly, before they cool down. You CAN mix by hand but it’s much more difficult and time consuming.
